Q.

The quantities which have the same dimensions as those of solid angle are:

  1. A

    strain and arc

  2. B

    angular speed and stress

  3. C

    strain and angle

  4. D

    stress and angle

Solution

Solid angle is dimensionless.

Among the choices, strain (ratio of lengths) and plane angle (ratio of arc to radius) are also dimensionless. Arc has dimensions of length, angular speed has , stress has pressure dimensions.
